Table B.1: Custom Data Table
B.3.2 Computing the Number of Files and Records
With the 16-megabyte, extended-memory option installed, the Model 931A
is limited to a maximum of 20 files. Beyond that, it is only the size and
the number of records that limit filling up the entire 16 megabytes.
Each type of record requires a fixed number of bytes of memory. When
the extended memory is cleared there are 16,777,216 bytes (16 megabytes)
available for data record storage. Divide 16,777,216 by the number of
bytes per record to determine the number of records that may be stored.
